772219 ÷ 39 
The aim is to understand the frequency of 39 in 772219.

Going ahead to step 1:
When dividing 7 by 39, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 39

On to step 2:
39 goes into 77 1 times with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 39 from 77 leaves us with 38.
Append the next digit (2) from the dividend to 38 and continue with: 382 / 39

On to step 3:
382 divided by 39 is 9 with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 351 from 382 to get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 39

On to step 4:
The number 39 fits into 312 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 198.0
The remainder is 0 after subtracting 312 from 312.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 39

Let's proceed to step 5:
The number 39 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 1980.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 39

Advancing to step 6:
If we divide 19 by 39, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 19800.0
Deduct 0 from 19 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
The number 39 fits into 190 4 times, leaving a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 19800.4
Subtract 156 from 190 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
When dividing 340 by 39, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 19800.48
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
39 can be fit into 280 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 19800.487
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
39 goes into 70 1 times with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 19800.4871
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
39 goes into 310 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 19800.48717
Subtracting 273 from 310 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 12:
370 divided by 39 is 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 19800.487179
Subtract 351 from 370 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 13:
39 goes into 190 4 times with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 19800.4871794
If we subtract 156 from 190, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
The number 39 fits into 340 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 19800.48717948
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 19800.48717948 with a remaining 2.8e-08.
